Dual WAN Starlink+SDWAN

[jsnider]

Hello Legends,
I'm struggling a little with a left of field setup which opnsense see's as DualWAN but isn't, the only actual connection is Starlink as WAN1, a 2nd "WAN" service provides a static public address but ultimately connects via opnsense LAN side to get access to the data center where it connects a tunnel which is connected to WAN2 for port forwards.

A wireguard VPN also connects over starlink for site to site VPN with the office.

The issues:
If I leave the default LAN firewall rule for outgoing traffic I get loss of connectivity for 20-40 seconds when I suspect opnsense is trying to use WAN2

If I hard code the LAN firewall outgoing rule to WAN1 - Starlink the connection is flawless but the LAN network can not access across the wireguard VPN.

I have adjust metric, priority and weight of WAN connections to favour Starlink but the dropouts still occour.

Thanks,
Jordan
